Lyocell filament lining fabric
A lining fabric (3) for a clothing article (1). The lining fabric (3) is hygroscopic to ensure good wearing comfort, and has sufficient dimensional stability to allow washing in a household laundry machine. The lining fabric (3) is made from yarns (6) containing or consisting of Lyocell filaments (7). The Lyocell filaments (7) have an average linear density of less than 1.5 dtex, preferably less than 1.4 dtex and even more preferred, less than 1.3 dtex. The washing shrinkage after five washings is preferably less than 4% in each of two perpendicular directions.
Sleeve Roll Belt
A sleeve roll belt (10) has an inner surface (11) and an outer surface (12). The belt has a body (15) and a reinforcing structure (30). The reinforcing structure (30) has first yarns (31) arranged to a first direction (D1) of the belt, and second yarns (32) arranged to a second direction (D2) of the belt. The reinforcing structure (30) also has auxiliary yarns (31b, 31c) arranged parallel or substantially parallel to the first direction (D1) of the belt, wherein the auxiliary yarns are arranged to a depth of greater than a depth of the first yarns, measured from the outer surface (12) of the body (15) to an outer surface (31-o, 31b-o) of each yarn (31, 31b, 31c) in the depth direction of the belt, and a diameter of the auxiliary yarns is at least 20% smaller than a diameter of the first yarns.

High-performance polyethylene multifilament yarn
Processes for making high-performance polyethylene multi-filament yarn are disclosed which include the steps of a) making a solution of ultra-high molar mass polyethylene in a solvent; b) spinning of the solution through a spinplate containing at least 5 spinholes into an air-gap to form fluid filaments, while applying a draw ratio DR.sub.fluid; c) cooling the fluid filaments to form solvent-containing gel filaments; d) removing at least partly the solvent from the filaments; and e) drawing the filaments in at least one step before, during and/or after said solvent removing, while applying a draw ratio DR.sub.solid of at least 4, wherein in step b) each spinhole comprises a contraction zone of specific dimension and a downstream zone of diameter Dn and length Dn with Ln/Dn of from 0 to at most 25, to result in a draw ratio DR.sub.fluid=DR.sub.sp*DR.sub.ag of at least 150, wherein DR.sub.sp is the draw ratio in the spinholes and DR.sub.ag is the draw ratio in the air-gap, with DR.sub.sp being greater than 1 and DR.sub.ag at least 1. High-performance polyethylene multifilament yarn, and semi-finished or end-use products containing said yarn, especially to ropes and ballistic-resistant composites, are also disclosed.

Method for measuring productivity of angora rabbit and its application
A method for measuring and analyzing the productivity of Angora rabbit is provided. Firstly, the Angora rabbit to be tested are simultaneously sheared at the age of 18 weeks, and are reared in a single cage to the age of 29 weeks according to standard conditions for test, and the individual consumption of Angora rabbit during the test period is recorded; secondly, the wool samples were sheared from the middle and upper part of the body side of the Angora rabbit with an electric wool clippers. The weight of the Angora rabbit, the weight of the wool sample, and the length of the wool fiber were measured and bagged for recording; in the third step, the wool fiber diameter of each wool sample was measured by fiber projection method; in the fourth step, the measured values were substituted into the given estimation formula.
Method of manufacturing fraying-free cotton elastane weft knit fabric
This invention is related to a method of manufacturing a cotton weft knit fabric that is resistant to fraying, curling, and laddering. The unique fabrication method described herein generates a cotton fabric that resists edge fraying and curling when cut. As a result of the unique manufacturing method described herein, the typical garment hemming process typically used to prevent hemming and fraying in weft knit fabric is not required.
